CANT-DOG.

Specification of Letters Patent.

Patented Nov. 29, 1910.

Application filed lviarch 7, 1910. Serial No. 547,941.

lb all whom it may concern:

Be it known that I, FRANoIs A. CLOUDY, a citizen of the United States of America, and a resident of the town of Startup, in the county of Snohomish and State of VVashington, have invented certain new and useful Improvements in Cant-Dogs, of which the following is a specification.

My invention relates to devices of the above type, having more particular reference to the construction of the hook member thereof, and has for its primary object to provide an adjustable tooth or fang which may be adjusted to vary the spacing of its point or gripping portion from the stem of the hook, to thereby adapt the cant dog hook for operation on logs or timbers of varying diameters.

A further object is to provide a tooth or fang of this character capable of adjustment to give its point or gripping portion a lateral projection.

With these and other objects in view, to be referred to as my description progresses, my invention resides in the features of construction and arrangement of parts, hereinafter described and succinctly defined in my annexed claim.

Referring to the accompanying drawing wherein my invention is illustrated in such form as now preferred by me, and in which like numerals of reference indicate like parts throughout: Figure 1 is a fragmentary elevation of a cant dog hook, equipped with my invention, the same being in partial section, and illustrating the tooth or'fang by broken lines in an adjusted position. Fig. 2 is a vertical section, on enlarged scale illustrating the tooth or fang, by solid and broken lines, adjusted to have projection on the opposite sides of the hook member, and Fig. 3 is section taken on line 33 of Fig. 1.

Referring to the drawing by numerals of reference, 1 indicates a tooth or fang, the point or gripping portion 2 of which is oifset or lies eccentric to the shank 3, whereby upon rotary adjustment of the tooth, the relative position of its point 2 with respect to the hook, as 4:, is varied.

As now considered, shank 3 is formed angular in cross section and is removably seated in a correspondingly formed socket 5, provided in an angular extension of the curved lower portion of the stem 7 of the hook member 4. Therefore to effect adjustment of the tooth or fang, the same must first be lifted partly from its seat or socket, and then given a quarter or half turn, as the case may be, the adjustment of the point toward and from stem 7, as illustrated in Fig. 1, obviously adapting the hook for operation on logs of relatively large and small diameters, while lateral adjustment of said point, see Fig. 9., enables operation on a timber, where, as is often the case, the operator is unable to operate the cant hook at a right angle thereto.

Tooth or fang 1 may be readily loosened by force applied to the lower end of its shank, which, as shown, projects through socket 5 at the rear side of a depending guard 9, which latter prevents such projecting portion of shank 3 striking an obstruction, and thereby being accidentally loosened or displaced, during operation of the device, as will be readily understood. In addition to the adjustable feature of the tooth or fang, as set forth in the preceding, by making the same removable, it can obviously be formed of a better grade of material than the hook proper, should this be desired, and-further such construction permits of a ready substitution of a new tooth for a worn or broken one, as is apparent.

lVhile tooth or fang 1 can be otherwise formed, I prefer to taper its shank 3, and provide its point or gripping portion Qby tapering the tooth proper in an upward direction to one corner or edge portion thereof, which edge portion is in alinement with and forms a continuation of the corresponding edge portion of the shank.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is

A cant dog hook having a socket angular in cross section and tapered, and a tooth tapered in opposite directions to provide a shank for engagement in the socket of said hook, and a gripping point, said gripping point bemg formed at the juncture of adjacent side faces which form continuations of and are in alinemcnt with the corresponding side faces of said shank.

Signed at Startup, Vashington, this 12th day of February, 1910.
